On July 30, 2025, India and the United States successfully launched the NASA-ISRO Synthetic Aperture Radar (NISAR) Earth observation satellite from the Satish Dhawan Space Centre in Andhra Pradesh, India. This joint mission, valued at $1.5 billion, marks a significant milestone in space collaboration between the two nations. The satellite, equipped with dual-band radar, can monitor Earth’s land and ice surfaces with unprecedented precision, capturing data through clouds and darkness to track earthquakes, landslides, glacier movements, and crop health in real time.
Details of Earth Observation Satellite
The NISAR satellite, orbiting at 464 miles, generates approximately 80 terabytes of data daily, offering insights into environmental changes and disaster management. Posts on X highlight the mission’s potential to enhance global understanding of climate and geological shifts, with users noting its ability to detect changes down to the centimeter. This collaboration between ISRO and NASA strengthens India-US ties and positions both nations as leaders in space-based Earth observation.
